Crows of the world

From the front flap: An eminent ornithologist here offers a wealth of information on all living corvid members. Derek Goodwin first covers nomenclature as well as adaptive radiation and plumage. He then gives an account of many aspects of crow behavior. He discusses sociability and flocking, communal roosting, threat and fighting, and self-assertive display. Also described are their reaction to the sick and injured, their individual differences, their nesting habits and care of the young, and their voice and vocal mimicry.
